Abstract
Methods include performing, by a terminal device, downlink control channel monitoring according to a first time pattern. The methods include determining that data has been transmitted on downlink on a number of symbols and based on the determination that the data is transmitted, suspending the performing of downlink control channel monitoring according to the first time pattern. The methods also include performing downlink control channel monitoring on at least one symbol after transmission of the data.
Claims7
A method, comprising:
- receiving, by a terminal device, configuration parameters for downlink control channel monitoring according to a first time pattern and a second time pattern;
- performing, by the terminal device, the downlink control channel monitoring according to the first time pattern, wherein the downlink control channel monitoring is performed on an unlicensed band;
- determining that data has been transmitted on the downlink on a number of symbols, wherein the determination that the data is transmitted is based on detecting downlink control information intended for a group of terminal devices;
- based on the determination that the data is transmitted, suspending the performing of the downlink control channel monitoring according to the first time pattern;
- performing downlink control channel monitoring according to the second time pattern on at least a next symbol after transmission of the data;
- performing downlink control channel monitoring according to the second time pattern at least for one next slot after the end of the transmission of the data, wherein the first time pattern has more than one downlink control channel monitoring occasion per slot and a second time pattern follows slot periodicity of 2 symbols or 14 symbols;
- determining, by the terminal device, that downlink transmission has ended;
- and
- based on the determination that the downlink transmission has ended, suspending the downlink control channel monitoring according to the second time pattern.

An apparatus, comprising least one processor;
- and at least one non-transitory memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to:
- receive configuration parameters for downlink control channel monitoring according to a first time pattern and a second time pattern;
- perform the downlink control channel monitoring according to the first time pattern, wherein the downlink control channel monitoring is performed on an unlicensed band;
- determine that data has been transmitted on downlink on a number of symbols, wherein the determination that the data is transmitted is based on detecting downlink control information intended for a group of terminal devices;
- based on the determination that the data is transmitted, suspend the performing of the downlink control channel monitoring according to the first time pattern;
- perform downlink control channel monitoring according to the second time pattern on at least a next symbol after transmission of the data;
- perform downlink control channel monitoring according to the second time pattern at least for one next slot after the end of the transmission of the data, wherein the first time pattern has more than one downlink control channel monitoring occasion per slot and a second time pattern follows slot periodicity of 2 symbols or 14 symbols;
- determine that downlink transmission has ended;
- and
- based on the determination that the downlink transmission has ended, suspend the downlink control channel monitoring according to the second time pattern.
